FINE VOLTAGE ADJUSTMENT
Adjustment of the output voltage from the generator is necessary to provide the correct voltage to the end of the
power line. Voltage adjustment can be carried out at any time on the Voltage Adjust screen.
Figure 3-6. Fine Voltage Adjustment
1. With the unit running, press .
2. Press . The voltages displayed will begin flashing.
3. Use ▲ and ▼ to adjust the voltage.
4. Press  to confirm the new voltage. The voltages displayed will stop flashing.
VOLTAGE SELECTOR SWITCH
The voltage selector switch mechanically changes the connections between the generator output leads and the
connection lugs on the main control panel. Voltage ranges are selected by rotating the handle on the switch to the
desired voltage.
NEVER change the voltage selector switch while the engine is running or the controller is
on. If the engine is running or starts while the setting is changed, severe arcing will occur
causing damage to the switch and generator windings.
The voltage selector switch is equipped with a lockout mechanism. Once the proper voltage has been selected,
insert a padlock through the lockout hole(s). By locking the handle in place, unauthorized changing of the voltage
setting is prevented.
